Description
Race Spec (RS) Rear Sprockets are CNC machined to precise tolerances from high quality, heat treated 7075-T6 aluminum alloy. Painstakingly engineered, they achieve optimum load distribution, unsprung weight savings, and tooth endurance. The result is a durable, featherweight and feature-packed sprocket unequaled in the market.
- Heat treated, precision CNC machined 7075-T6 billet aluminum construction for the ultimate in lightweight strength
- Exclusive Angled Mud Groove design allows sprocket to self-clean during operation, preventing dirt buildup that leads to horsepower loss and sprocket wear
- Deep penetrating anodized finish protects against corrosion, improves wear resistance
- Carefully engineered window pattern reduces unsprung rotating mass without compromising strength
- Machined edge chamfers eliminate sharp edges, reduce weight, and make for a cleaner appearance
- Countersinks automatically center sprocket to hub during installation-no hub center guide needed
- Machined inlay for subsurface sticker location
- Made in USA
